public class HardHeaded_Offering
extends OfferingStrategy

This is the decoupled Offering Strategy for HardHeaded (ANAC2011). The code was taken from the ANAC2011 HardHeaded and adapted to work within the BOA framework. >>Extension of opponent model>> As default the agent uses the frequency model to select the best bid from a small set of bids. The agent is extended such that other models can be used. If no opponent model is given, then a random bid is chosen.
